The square is a geometric shape that is related to the four sides family because it has four sides.

The four sides are the same length and are parallel to each other. What does this mean exactly? It means that two sides are parallel to each other, and the other two are parallel to each other as well.

The four interior angles of a square each equal 90º, or in other words, it is a right angle. The sum of all angles are added together; they add up to 360º. The two diagonals that a square has are equal in length, and the point where they cross is the square’s center.
